specific Embodiment approach 1

[0018] The specific embodiment one, the image shooting method of stroboscopic scene, it comprises the following steps:

[0019] Step 1. Use a vibration decibel tester and a light tester to monitor the vibration decibel value and light value of the shooting environment in real time, and adjust the parameters of the camera according to the obtained vibration decibel value and light value;

[0020] The parameters include sound decibel value, light intensity, etc., which are adjusted to the best according to the situation at that time. You can record the current parameter range for future reference.

[0021] Step 2. Aim the camera at the scene to be shot, and use the Fourier transform method to achieve the focus between the camera and the scene to be shot by setting the threshold of the transformed energy concentration; the specific method is:

[0022] 1. Set different focal lengths and take pictures.

[0023] 2. Perform Fourier transform on the photo to obtain a frequency domain...

specific Embodiment approach 2

[0031] Embodiment 2. This embodiment and the image capturing method of the stroboscopic scene described in Embodiment 1 are characterized in that the process of shooting in step 3 is completed in a dark box.

[0032] In the following, the screen is used as the scene to be shot to verify the shooting effect of this embodiment:

[0033] Implement real-time monitoring of the shooting environment, implement through vibration decibel testers, light testers, etc., adjust the brightness and contrast of the display at the sending end, and realize the comprehensive optimization of the camera's ISO sensitivity, gain, and shutter speed;

[0034] Implement to determine whether the camera and the screen are aligned, display a square on the screen, install a level on the camera, view and fine-tune through the real-time acquisition function of the camera; use Fourier transform and other methods to judge by setting the threshold of energy concentration Whether the focus meets the shooting req...

specific Embodiment approach 3

[0040] Specific embodiment three, adopt the processing method of the stroboscopic image that the image capture method of stroboscopic scene described in specific embodiment one obtains, it comprises the following steps:

[0041] Step A1. For the grayscale stroboscopic image, perform a binarization operation to obtain a binarized image; for a color stroboscopic image, perform an adaptive multi-valued operation to obtain a multi-valued image;

[0042] Step A2, performing a deburring operation on the binarized image and the multi-valued image obtained in step A1, to obtain a processing result of the stroboscopic image.

[0043] The method for improving the photo shooting quality of stroboscopic scenes such as high-speed switching and refreshing flickering in the present invention provides a specific operation method for similar scenes to improve the quality of photo shooting; the image processing method is used for stroboscopic scenes such as high-speed switching and refreshing fl...

Abstract

The invention discloses an image shooting method under a stroboscopic scene and a method for processing stroboscopic images obtained by using the image shooting method, relating to the field of image processing and solving the problems that the effect of an image shot under a stroboscopic scene is poor and the image shot under the stroboscopic scene has low image definition after being processed, currently. The image shooting method comprises the following steps of: monitoring a shake decibel value and an illumination value of a shooting environment in real time, and adjusting parameters of a vidicon according to the monitored values; aligning the vidicon to a scene to be shot, and realizing focusing between the vidicon and the scene to be shot by adopting a Fourier transform method and setting a threshold value of energy concentration degree after transform; and setting a shooting frequency of the vidicon and then shooting. The method for processing the colored images comprises the following steps of: carrying out binaryzation operation and deburring operation on a gray-scale stroboscopic image; and carrying out self-adaptive multiple-valued operation and deburring operation on a colored stroboscopic image. The image shooting method and the method for processing the stroboscopic images, disclosed by the invention, are suitable for shooting images under the stroboscopic scene and processing the shot images.

Description

technical field [0001] The invention relates to the field of image processing. Background technique [0002] At present, there has been a lack of systematic and practical image capturing methods and image processing methods for high-speed switching, refreshing, flickering and other stroboscopic scenes. Existing technologies generally use hardware devices to fix (such as the invention patent with publication number CN 101527787), or use brightness matrix to process static images (such as the invention patent with publication number CN 1620102A) to obtain high-quality photos. Although these methods can achieve the purpose of obtaining high-quality photos, they need to use fixed hardware and target static scenes, and the image processing capabilities are severely limited. [0003] Various existing photo shooting technologies generally focus on conventional scenes to consider shooting problems, such as sufficient lighting, static images, relatively easy focusing, etc., and cann...
